Improved boot-crimping machine



UNITED STATES PATENT @Erica JOHNS. LANDES, OF LANCASTER, PENNSYLVANIA, ASSIGNOR TO HIMSELF `AND HENRY G. HALBAGEL'OF SAME PLACE.

IMPROVED B'OOT-CRIMPING MACHINE.

Specification forming part of Letters Patent No. 116,427, dated February 14, 1865.

1'0 all whom it may concern:

Beit known that I, JOHN S. LANDES, ofthe city of Lancaster, in the county ot' Lancaster and State of Pennsylvania, have invented a new and Improved Mode of Constructing Machines for Crimping Boots; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, making a part ot' this specification, in which- Figure l shows the shape and connection of the three central pieces ot hard and well-seasoned wood ot the requisite size and thickness, (marked A B C.) Fig. 2 shows the same covered on each side by the sheet iron plates D E; Fig. 3, the same with the crimped leather in place, held by the three clamps L, peculiarly adapted to the same. Fig. 4 illustrates one of those clamps.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

The triangular piece A has its lower edge or side and rear edge or side so as to embrace an angle of about one hundred degrees, (shown by the dotted lines at right angles to the baseline,) both inner sides tapering in the manner shown from the central core, (marked a,) which projects at a right angle with the tapering' sides the height ot' the shin and instep piece C B at their narrower ends, as shown, and are held by a leather hinge, c a b, Fig. 2, to the central core, c, ot' or on the main piece A. The shape and connection are clearly shown of the pieces A B C, Fig. 1, forming the central part of the machine. The sheet-iron plates D are fastened on each side to the shin-piece G and connected together at N by arivet. To avoid the same in its operation, a notch, a, is cut ont of the upper rear corner of the piece A. The sheet-iron plates E are fastened on each side to the instep-piece B, and held in place by a staple, e, in the lower inner corner, overlapping the plates D, so as to allow said plates D to slide under in their motions while operating the stretching-screws F G. This screw G enters the back or edge ofthe piece A above, and the other screw, F, the lower edge or base, as shown. Afemale screw, H, is also inserted into the block or piece A for each screw, operating against an iron plate, K, opposite them,

respectively, in the hinged pieces U B, so that theaction of the handled screws will throw out the several hinged pieces C B above and below in the act ot'crimping. The lower plates, E, are also attached to each other by a rivet, N, and a similar notch, n, is shown in A below as above for the like purpose.

To use this machine, the leather is cut andy prepared in the usual manner and folded over the machine, and the-sides drawn down by means of the three clam-ps L L L", as shown by Fig. 3. The operation is then finished by turning the handled screws F G, thereby forcing out the shin-piece G and instep-piece B, giving the leather the desired set and crimping more eft'ectually, aided by the clamps peculiarly adapted to this machine and essential to its perfection.v These clamps, Fig. 4, have a spring-plate, R, on top, with a gripping-dan ge operating into a notch on the jaws Q, above and below. There is a thumb-screw, P, on each spring R andjaw Q. The spring-catch is slackened and the leather on one side seized and held by it, while the opposite jaw and spring in like manner hold the leather on that side. These jaws, being united by a back brace in which a screw-thread is cut (for the screw with its turning-eye S) aid in forcing and stretching the gripped leather by coming in contact with the crimping frame or edge by the united laction and proper adjustment ot' the stretching-clamps L and forcing-screws F G. The most pertectcrimpin g is accomplished without the use ot' tacks vand tedious process commonly employed. There is a square notch, I,-in the beveled angle or heel of the main piece or block A, into which the central clamp, L", sets.

The operation of the shin-pieceGand insteppiece B, both attached with a leather hinge, a b c, to the central projecting curved portion, a, ot' A, in combination with the sheet-iron plates or facings D E, I deem a. novel combination, having a peculiar actlon upon the leather when held by the several clamps with their double spring-jaws properly adjusted by the mechanic.

Clamps of a similar construction may be in use, though I am not aware of any su bstantially the same. I however do not claim the clamps used otherwise than in combination with my crimper.

It will be seen that the main piece or body A is not attached to the sheet-iron plates D Ef rlhcy slide independently with the motion given to the portions C B by the long-handled screws F G, operating against them at or on the plates K, 'forcing` them out separately, car! rying the plates D E in their motion as they7 slide under or within the staple e byits roundedy 1. The construction and arrangement of the pieces B G, connected by aA hinge, a b c, to the centralV projection, a, on the base-pieceA, with the two handled screws F G in A acting on said pieces B C, respectively.

2. The pieces B C and their hinged attachment to A, in combination with the sheet-iron plates D E and their attachments, respectively, in manner shown, foroperating upon the leather held by the clamps L Lll L" by means ot' the handled screws F G, all arranged and operating substantially in the manner set forth, for the purpose specified.

JOHN S. LANDES.
